MichiAruki Privacy Policy

Last updated: August 13, 2026

About the app · Support · 日本語

MichiAruki ("the App") is provided by TempuraApps ("we"). This policy explains how the App handles user information.

1. Information we collect

The App does not collect personal information such as your name, email address, or phone number. Everything you record or enter — your walks and their routes, visited areas, favourite spots, and notes — is stored only on your device and is never transmitted to or held on servers operated by us or by third parties. The only exceptions are the place search described in section 2, the usage measurement described in section 4, and the Pro purchase processing described in section 5, each of which sends a limited set of information to external services. None of them includes your name or the content you record or enter, and none of them can identify you personally.

2. Location data

The App uses your location to record your walks and to suggest directions and destinations you have not walked yet. The location data and routes it obtains are stored only on your device and are never transmitted to or held on servers operated by us or by third parties. Location data is passed neither to our analytics (section 4) nor to purchase processing (section 5).

Recording continues while your screen is locked, because a walk is normally taken with the phone in a pocket. The App only ever asks for "While Using the App" access; it never asks for "Always". Recording continues only between the moment you start a walk and the moment you end it.

The one exception to the above is place search: when you look for a destination or a starting point (a park, a café, and so on), the coordinates of the surrounding area and your search terms — including any words you type — are sent to Apple's map service (MapKit) as required for that search. That communication is handled under Apple's privacy policy; it does not pass through our servers and we do not store it. Your walk records, routes, and saved spots are never included in that search. You can change the location permission at any time in your device's Settings.

3. Accounts and network use

No account registration is required to use the App. The data you record or enter stays on your device and is not transmitted externally. The App does, however, communicate with a limited set of external services for destination search (section 2), for the usage measurement described below (section 4), and for purchase processing (section 5).

4. Usage analytics (PostHog)

To improve quality and features, the App measures anonymous usage with the analytics service PostHog. What is collected is limited to the type of action taken — launching the App, using a feature, opening the paid plan screen, purchasing a paid plan (monthly or annual, and whether it went through), restoring a purchase — together with statistical information such as counts and categories that accompany it. We do not send personal information such as your name or email address, nor the content you record or enter (walk routes, location data, spot names, free-form notes, and the like).

Actions relating to MichiAruki Pro are included as one of these action types: that a purchase or restore was started, which plan it was for, and whether it succeeded or failed. No payment details, amounts, or transaction identifiers are sent, and none of it is linked to you personally.

Technical information automatically attached by PostHog may also be included: the App version, your OS type and version, your device type, and the App's display language. Your time zone is stripped before sending, because it can be used to infer your approximate region. IP addresses are configured to be discarded on the analytics side, and we have specified that no region or location be inferred from them. Finer locations such as your city or your coordinates are never collected. None of this is intended to identify a specific individual, and none of it is linked to an account. The data is stored in the EU region.

Each record sent carries an anonymous identifier created for that installation of the App. It exists so that actions from the same installation can be read as one thread. It is not tied to your name, email address, account, or any hardware identifier provided by the device, and we do not use it to identify you. Deleting and reinstalling the App produces a new one.

We have no way to connect that identifier to you as a person. For that reason we cannot act on requests to retrieve or delete one user's data individually. If you wish to stop the measurement entirely, please delete the App; nothing is sent after it is removed.

The App does not serve advertising or perform advertising tracking (IDFA and similar) of any kind. Nor do we use the information collected for advertising purposes, or provide or sell it to third parties.

5. Purchases (RevenueCat)

Purchases and restores of the App's paid features (MichiAruki Pro) are handled through Apple's App Store, and we use the subscription infrastructure service RevenueCat to manage purchases and entitlement status. Information such as your purchase status is therefore processed by RevenueCat. Payment details such as credit card numbers are handled by Apple and are never received by us. Purchases are managed under an anonymous identifier and are not linked to personal information such as your name or email address. Please note that RevenueCat is a service provided by a company based in the United States.

6. Data backup

The App can export your recorded data as a file (in JSON format). An exported file is placed in the location you choose and is under your control. We do not access it.

7. Provision to third parties

We do not provide or sell your information to third parties for advertising purposes. Information sent to the external services described in sections 4 and 5 (PostHog and RevenueCat) for measurement and purchase processing is handled under each service's own privacy policy.

8. Deleting your data

Data stored on your device can be erased using the App's delete and reset features, or by deleting the App itself. What “Delete all data” in Settings covers is listed on the confirmation screen inside the App; settings such as the theme are kept. To be certain everything stored on the device is erased, delete the App itself.

9. Children's privacy

The App is not directed at children under 13, and we do not knowingly collect personal information from children.

10. Changes to this policy

We may revise this policy as features are added or changed. If a change is significant, we will announce it on this page.
